(3) XVII, 22-24, 23 to 25 mm. long (a very large specimen.) 



(4) XIX, 19-22, 20 mm. long. 



(5) XX, 20-23. 



(6) XXIV, 21, 17 to 20 mm. long. 



(7) XIX, 21-25 (usually about 23), 20 mm. long. 



(8) XXII, 21-24, 20 to 22 mm. Jong. 



(9) XXII, 21-23, 20 to 23 mm. long. 



One of the specimens is interesting in possessing 11 arms, one IIBr 



2 series being developed. This is the first time that the presence of 



'IIBr series has been detected in this genus, though T. picta not 



infrequently has 12 arms through the presence of an additional ray.

1. Madagascar; Doctor Hildebrandt; Cat. No. 2546. — One speci- 

 men, labeled "Actinometra Solaris." 



2. Mauritius; M. Guerin-Meneville; Cat. No. 1038. — One specimen; 

 the cirri are XIX, 21-23 (usually 22 or 23), 15 mm. long; the carina- 

 tion on the arms is veiy greatly developed as in certain specimens 

 of T. picta from Rio de Janeiro, each carinate process bearing a tuft 

 of small spines. The color is purple. 



3. Mauritius; Cat. No. 1037. — One specimen; the cirri are XXII, 

 23-26, 20 mm. long; the arms are about 80 mm. long; the color is 

 white, faintly blotched with light brown. 



4. Fouquet Reef, Mauritius; Prof. K. Mobius; Cat. No. 5349. — 

 Twenty-six specimens. Details of six of the largest and most typi- 

 cal are: 



(1) Cirri XV, 20-23 (usually the latter), 20 mm. long; the dorsal 

 pole of the centrodorsal is flat, 5 mm. in diameter; the arms are very 

 strongly carinate; the color is plain dark purple. 



(2) Cirri XXIII, 21-24 (usuaUy 22 or 23), 20 mm. long; the dorsal 

 pole of the centrodorsal is flat, 4 mm. in diameter. 



(3) Cirri XXVI, 21-25 (usuaUy 23 or 24), 20 mm. long; the arms 

 are strongly carinate. 



. (4) Cirri XX, 22-24 (usually 23), 15 to 20 mm. long; the arms are 

 about 100 mm. long. 



(5) Cirri XX, 2.3-25 (usually 23), 15 to 20 mm. long; the dorsal 

 pole of the centrodorsal is flat, 7 mm. in diameter. 



(6) Cirri XIX, 22-23, 15 to 20 mm. long. 



• In these specimens the carination of the brachials is usually promi- 

 nent. The color is usuaUy plain purple, but some specimens have 

 narrow yeUow bands in the distal part of the arms. 



5. Zanzibar; Count von der Decken; Cat. No. 1636. — One specimen.
